This repository contains a custom Transformers causal language model. External evaluation repositories should load it with trust_remote_code=True and use the causal backend.

Install the runtime dependencies before loading the model:

sentencepiece is required for AutoTokenizer. pypinyin is required for raw Mandarin-to-pinyin tokenization. jieba is required when use_jieba is true; this export was created with use_jieba=true.

Configure external evaluators with:

The tokenizer accepts raw text through standard calls such as tokenizer(text), tokenizer(text, add_special_tokens=False), and tokenizer(texts, padding=True, truncation=True, return_tensors="pt"). It also accepts return_offsets_mapping=True for compatibility with completion-ranking evaluators that need suffix masks. The model supports output_hidden_states=True for representation extraction tasks.

This export sets patch_pathlib_utf8_open=true in config.json. When loaded with trust_remote_code=True, the config installs a narrow Windows compatibility shim so later text-mode Path.open("r") calls without an explicit encoding default to UTF-8. Set PINYIN_CODE_DISABLE_UTF8_OPEN_PATCH=1 before loading the model to disable that shim.
